The Foundation of our Formulas

Hadasei-3: Our Proprietary Stress-Barrier Complex

Three Japanese ingredients, double-fermented to unlock 400+ micronutrients that synchronize the skin's renewal cycles and boost resilience to daily stressors for visibly smoother, firmer skin.

“Hadasei-3 is powered by time-tested ingredients that are the cornerstone of the Japanese diet and attributed to longevity and health.”

Vicky Tsai, Tatcha Founder

Rooted in the Nutrient-Rich Japanese Diet

A proprietary complex of three ingredients, each chosen with precision, each sourced from a specific region of Japan where the conditions for growing them are perfect and nowhere else on earth quite replicates.

Uji Green Tea

From the misty hills outside Kyoto where green tea has been cultivated for over eight centuries. Helps neutralize oxidative damage to reduce signs of premature aging.

Okinawa Algae

From the waters surrounding the island where the population has long been studied for its exceptional longevity. Helps moisture retention with skin-plumping polysaccharides.

Flood Skin with Deep Hydration

Hadasei-3 doesn’t just sit on the skin’s surface. It actively drives moisture deeper for visibly transformative hydration.

Frequently asked questions

What’s the meaning behind the name "Hadasei-3"?

In Japanese, “hada” (肌) means skin, and “sei” (生) means “life.” The “3” refers to the three foundational ingredients that power the complex: Akita rice, Uji green tea, and Okinawa algae. Together, these ingredients form our proprietary complex to reveal healthy, radiant skin.

How did the Tatcha institute land on the 3 ingredients in Hadasei-3 and why are they significant to the Japanese diet?

Hadasei-3 was inspired by the nutrient-rich Japanese diet, widely regarded as one of the healthiest in the world, and Japan’s long tradition of hakkō (発酵), or fermentation, a practice used for centuries in Japanese food and wellness. Through research into traditional Japanese beauty rituals, we explored how nutrition and skin have long been connected in Japan.

The Tatcha Institute in Tokyo focused on three ingredients deeply rooted in the Japanese diet and sourced from regions known for their exceptional quality: Akita rice, Uji green tea, and Okinawa algae.

Crafted with a proprietary yeast and double fermented rice along with algae and green tea, Hadasei-3 is a complex rich in lactic acid, amino acids, antioxidants, and nutrients that support healthy-looking skin.

Why is Hadasei-3 significant to a Japanese skincare ritual?

In Japanese skincare, the step known as skin lotion (化粧水) is foundational, a lightweight liquid applied after cleansing to prepare the skin and help subsequent products absorb more effectively. This step traditionally did not exist in Western skincare. In the Japanese skincare ritual, it is essential to replenish moisture immediately after cleansing. Compared to a typical lotion, The Essence penetrates the skin more quickly and delivers a greater amount of hydration.

Based on this idea, the Tatcha Institute in Tokyo created The Essence, formulated with 100% Hadasei-3™, to deliver nourishment and hydration while priming the skin.

Why is Hadasei-3™ used as a base in most Tatcha products?

During development, the Tatcha Institute in Tokyo discovered that Hadasei-3 could function as a nutrient-rich base rather than just an added ingredient. As a result, our formulas are rich in lactic acid, amino acids, antioxidants, and nutrients from the very first step, supporting hydration while nourishing the skin. This reflects Tatcha’s philosophy of intentional formulation, where every ingredient is chosen to benefit the skin.
